What factors affect soil formation?
The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time. If a single parent material is exposed to different climates then a different soil individual will form.
Which factor does not lead to soil formation in nature?
Explanation. Polythene bags are not involved in soil formation. However, plastic bags are threat to environment, because these bags are non-degradable, i.e., do not decay and thus, do not lead to soil formation.

What are 3 things that affect soil?
Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place.
Which of the following is not important for soil formation class 10?
question. Option 4 duration of the day is not important for soil formation.
Which natural force does not lead to soil erosion?
Thus, the correct answer is 'Deforestation.
What are the 4 factors affecting soil erosion?
Vegetation, rainfall, soil, and topography are the primary factors influencing soil erosion, although other factors may be involved. The kinetic impact of rain hitting the soil causes water erosion (5, 6), and water erosion will occur when rainfall exceeds a certain value in a single rainfall event.
What are the factors affecting soil formation class 10?
Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place.
What factors affect soil formation in India Class 10?
Relief features, parent material, atmosphere, vegetation and other types of life, as well as time away from human activities, are the key factors responsible for soil formation.
Which one of the following is not a factor in the formation of soil * relief parent rock depth climate?
Expert-verified answer There are various factors of soil formation, but depth is not a factor. It is an attribute of soil. After soil formation, texture, layering, processes of formation and minerals can be examined by studying the depth of the soil.
Which of the following factors is not responsible for soil formation * A rainfall B Colour of rocks C humus D slope of the land?
Answer. The factor not responsible for soil formation is B. Colour of the rocks.
What are the 5 effects of soil erosion?
Impacts of erosion
- reduced ability of the soil to store water and nutrients.
- exposure of subsoil, which often has poor physical and chemical properties.
- higher rates of runoff, shedding water and nutrients otherwise used for crop growth.
- loss of newly planted crops.
- deposits of silt in low-lying areas.

Which of the following is the effect of soil erosion?
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

And degraded lands are also often less able to hold onto water, which can worsen flooding.
Which of the following is not an agent of erosion?
The correct answer is an option (d). Explanation: The main agents of erosion and deposition are winds, running water, glaciers and sea waves. Volcanoes are not an agent of erosion and deposition.
Which of the following factors does not affect the weathering of rocks?
Water is the most influential factor out of all the factors of climate in order to bring about the weathering of rocks. Decomposed material does not contribute to the weathering of the parent rock.
What are the 4 types of soil erosion?
Different Soil Erosion Causes
- Sheet erosion by water;
- Wind erosion;
- Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
- Gully erosion – when water runoff removes soil along drainage lines.
- Ephemeral erosion that occurs in natural depressions.

Which of the following do not cause soil pollution?
Vehicles do not directly cause soil pollution. Deforestation, excessive use of fertilizers and solid wastes may cause soil pollution.
Which of the following is not an agent of weathering?
Soil is the material which is formed as the result of wethering hence it is not the agent of wethering and this is the right answer.
What is soil erosion Class 7?
Removal of the soil's upper fertile layer (topsoil) by strong wind and water flow is known as soil erosion. It takes away the soil's fertile layer and making the soil infertile and unsuitable for plant growth. Soil erosion is happening because the soil becomes loose due to the absence of plants.
Which of the following do not cause of soil population?
(A) Jute bags do not cause soil pollution Jute's most significant characteristic is that it is biodegradable and therefore does not damage the environment. It produces no trash and helps to keep the environment clean.

Which of the following is not an agents of erosion?
The correct answer is an option (d). Explanation: The main agents of erosion and deposition are winds, running water, glaciers and sea waves. Volcanoes are not an agent of erosion and deposition.
What are the 4 main weathering agents?
Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
How soil pollution and soil erosion could be prevented write any two measures?
(i) Recycling of non-biodegradable wastes. (ii) Limiting the use of pesticides and insecticides. (iii) Making dumping grounds of non-biodegradable wastes far away from fertile land. The removal of land surface by water, wind or ice is known as erosion.
